Give this exercise a try incorporates both isometric and isotonic principles! ✔️ Isometric: targeted muscle stays the same length ✔️ Isotonic: targeted muscle shortens At the start of the movement, the external rotators are actively shortening (isotonic). As you go into flexion, the external rotators maintain a static hold and don’t change length (isometric).
